The GTVHacker group gave this presentation at DEFCON 22. The group is famous for Hacking the Google TV a few years back, and in this talk they add plenty of devices to their credit. “We’ve taken all of our previous experience exploiting embedded devices and used it to bring you a presentation filled with more […]

Acoustic impulse marker
Adam Wrobel and Michael Grisanti of Cornell University built this device that tracks sound impluses: The core of our system is hardware based analog circuit, which filters, amplifies, and processes the sounds obtained from the microphones. By utilizing hardware for this, we are able to high frequency signal processing without taxing the microcontroller. Also, we remove […]
Remaking MSR206 RS232 magnetic card reader to USB
An article on modifying MSR-206 magnetic card reader to replace RS232 port with USB by crimier: This was of high urgency, so I’ve had to suspend my usual work activities and concentrate on this project yesterday. MSR-206 is a pretty impressive piece of technology, incomparable to those cheap eBay magnetic card readers. It even includes 24V […]
Derbycon video: Making BadUSB Work For You
Adam Caudill and Brandon Wilson gave this presentation at the recent Derbycon 2014 conference in Louisville, KY, covering their hack of the Phison 2251-03 USB controller firmware to add new “features” and functionality. They focus on the Patriot Supersonic Xpress 8GB USB drive allowing it to be repurposed for non-standard uses. Adam has posted his […]
I2C injection with the Bus Pirate
David Um writes: I decided to create a simple lab involving an Arduino Uno, in this case a SparkFun RedBoard, and a BlinkM LED that can be controlled over I2C. The Arduino would have a simple sketch that will update the color of the BlinkM and using a Bus Pirate I would then sniff traffic […]
DIY bluetooth door lock
An open source bluetooth door lock, check out the step by step tutorial here at Make: To open the lock, we will use the app LightBlue. It has a section called the Sandbox, that lets you control the LightBlue Bean without having to program your own iOS app. When the LightBlue Bean receives a serial message, it checks […]
Thermostat remote temperature sensor hack
Alan Parekh of Hacked Gadgets writes: We all have thermostats in our houses but how often are they in a horrible place? You often want to place the temperature sensor in a different location than the control and display unit. There are lots of models that have remote sensor capability but they come with a […]
Simple constant current driver for a high power LED
Elmars Ositis has been working on a simple constant current driver: In my previous post, I slapped together a quick LED lighting solution for my workbench… but it is truly a hack. What I really want to do is make a simple constant current driver, so the power LEDs can be used in other projects. One […]
Adding bluetooth to an EEG headset for mind-controlled projects
An instructables on adding bluetooth to an EEG headset for mind-controlled projects by AndreLe: I had serial bluetooth module HC-06 lying around and decided to see if I could integrate the two and skip the Arduino altogether. Turns out, it works almost as good as the commercially available NeuroSky MyndWave for a quarter of the […]
DEFCON 22: WarKitteh – cat on the warprowl
Why do the wardriving yourself when your cat can do it for you? Gene Bransfield gave this presentation at the recent DEFCON 22 conference, describing his efforts to use domestic pets wearing WiFi sniffer/GPS logging gear to essentially warprowl for WiFi hotspots. There’s also DoSdog, a standard pooch wearing a backpack concealing a Hak5 Pineapple, […]
Teensy MIDI USB foot controller for controlling Mobius Looper
Thrifleganger wrote this instructable detailing his Teensy MIDI USB foot controller for controlling Mobius Looper: The concept is quite simple and straightforward. You press a button, the arduino interprets the signal arriving from the button as a midi “control change” signal (typically represented as MIDI CC), and this signal can be mapped to respond to any of […]
Node-RED hacking – audio library front-end
Paul over at Dorkbotpdx writes: When I started the Audio library, a nice GUI (like Puredata or Max/MSP) seemed an impossibly distant dream. Then, in this forum thread, I learned of the open source Node-RED project. Over the last few days I’ve been coming up to speed on modern Javascript tools like jQuery and D3, to […]
Audio: Headphone “Anti thump” delayed output rev 1.1
Rupert Hirst writes: A long awaited refresh, to my previous “Anti Thump” headphone output delay circuit, designed back in 2011. The Idea behind the circuit is to introduce a small delay, during initial power up, to electrically isolate and protect equipment connected directly to an amplifier. Often, during power up, amplifiers can produce an audible […]
Adding speech to your Embedded project
SkinnySatan writes: I had this one project where the device was supposed to speak out the output. And I was too Lazy to actually go and build a PC based application and not that lazy to make it on a micro controller. So here is some of my research where i am gonna show you […]

An all-in-one, water and sand resistant, solar charger, audio speaker system, and sunburn timer calculator by starwisher. Check out the project’s instructables page here: This Instructable harnesses the power of Arduino, a UV sensor, and simple mathematics to make one nifty gadget sure to boost your outdoor summer fun – and minimize your indoor summer recovery!
Breaking out a QFP Attiny88 AVR
Ralph Doncaster writes: Several months ago I noticed the Attiny88. It has several more I/O than the Atmega328, with an extra Port A and PC7. And unlike most of the other Attiny series, it has real SPI instead of USI, so libraries using SPI don’t have to be re-written. At just 86c for qty 1, it […]
DIY automatic water timer
Kyle wrote an article detailing his DIY automatic water timer: Now that I have power and output figured out, I need to work on the control aspect. 555 timers are great for simple applications requiring up to a few minutes of delay. At 10 minutes, the RC values needed would boarder the danger zone of the timer not functioning […]
The Nanite 85
cpldcpu writes: Recently, Olimex anncounced the Olimexino 85s, claimed to be the “World’s smallest Arduino ever“. Now, that looks like a challenge. I guess it is about time to show off what has been on my desk since some time last year: The Nanite, pictured below. I designed this board for fun after the Digispark […]
Mini FM transmitter
electronics-diy shows you how to easily make a mini FM transmitter: It transmits FM waves so you could easily receive the signals on your mobile phone, radios, etc. As the name and the picture indicates it is very small and is approximately the size of a 9v battery clip. With this FM transmitter you could […]
How to hack a manual control into a cheap DMX dimmer
This article shows how to hack a manual control into a cheap DMX dimmer by Miceuz and Rxdtxd of wemakethings; One of our friends wanted to have a manual-control LED dimmer for his stop motion setup. We had several of these cheap Chinese DMX dimmers. How does one adds potentiometer control to something like this? Just cut […]
